Science with the VO: Spectroscopic Studies of Herbig Ae/Be Stars

Abstract

Abstract. The Virtual Observatory (VO) is opening up new ways of exploiting the huge amount of data provided by the ever growing number of ground-based and space facilities. Using VOSpec, a multi-wavelength spectral analysis tool developed by the ESA-VO Team at ESAC, and new developments on scripting with VOSpec (VOScript), we have started to undertake a comprehensive study of spectroscopic and photometric data in the VO on Herbig Ae/Be stars. By studying line strengths, variabilities and spectral energy distributions, from the X-ray to sub-millimeter ranges, we aim to gain insights into processes and disk properties of a large sample of these objects. This paper presents initial findings of the spectroscopic analysis and initial spectral energy distribution classifications.

Tracing Accretion onto Herbig Ae/Be Stars Using the Brγ Line

“…The values of m 12 − m 60 , L N IR , and L IR are available in Table 4. We determine the group classification this way for 110 objects (and for analysis we use an additional four from the literature for the IGRINS Sample, including for MWC 137 which is a group III object in Baines et al 2012 and an additional one from the literature for the Auxil-iary Sample). Of these 110 determinations, 69 are from the IGRINS Sample (34 Group I and 35 Group II) and 41 are from the Auxiliary Sample (25 Group I and 16 Group II).…”
